Computers work with binary math. This means 0 and 1 but how can we get output like pictures, sound, decimal numbers. These 0’s and 1’s are converted into decimal and another type of data. One of the most used convert types is ASCII.
计算机可以使用二进制数学。 这意味着0和1，但是我们如何获得图片，声音，十进制数字之类的输出。 这些0和1转换为十进制和另一种数据类型。 ASCII是最常用的转换类型之一。
美国国际交换标准代码 (American Standard Code for International Interchange)
ASCII is an acronym for American Standard Code for International Interchange . This standard is developed to serve a common data format between different IT systems. It is widely used in IT systems in the ’70s, ’80s, ’90s. But currently, UTF8 and more flexible and rich formats are gaining popularity.
ASCII是“ American Standard Code for International Interchange的缩写。 开发该标准以服务于不同IT系统之间的通用数据格式。 它在70年代，80年代，90年代的IT系统中广泛使用。 但是目前，UTF8和更灵活，更丰富的格式正在流行。
ASCII表 (ASCII Table)
ASCII table provides the equivalent presentation of the given characters to numbers. Look to the following ASCII table which starts from 0 and reaches 127 which is a total of 128 characters. 128 characters can be expressed as 7 bit.
ASCII表提供了给定字符与数字的等效表示。 查看下面的ASCII表，该表从0开始到127，共128个字符。 128个字符可以表示为7位。
扩展ASCII(Extended ASCII)
ASCII also provides more than 128 characters to comply with other languages and character sets. This is called Extended ASCII and starts from 128 and reaches to the 255. So with extended ASCII 8 bit or 1 byte is used. Extended ASCII provides character like Ç which is a character used in the Turkish language.
ASCII还提供了128个以上的字符以符合其他语言和字符集。 这称为扩展ASCII，从128开始到255。因此，对于扩展ASCII，将使用8位或1个字节。 扩展ASCII提供类似于Ç的字符，这是土耳其语中使用的字符。
